Need some customization

Dear Author,

I liked your wp pro quiz plugin. this is one of the best quiz plugin I found. I have started using this plugin for my website users. However, I want to maximize the use of this plugin and therefore want some level of customization.

Some of the customization are as follow:
– Each question can belong to multiple categories.
– Instead of creating questions directly within quiz, categories should be used to quiz.
– Quiz should be opened in Model popup window instead of same page.

Please let me know if above can enhanced with existing plugin. I need several more enhancements along with above. I am ready to pay for the effort. Please mail me at techarticles5 at gmail dot com
